SHUTTLE-Box MoTloN FOR Loolvls.

SPECIFICATION forming part of Letters Patent No. 551,191, dated December 10, 1895.

Application filed January 7, 1895. Serial No. 534,009. (No model.)

-To MZ whom t may concern:

Be it known that I, THOMAS LYNN, a citizen of the United States, residing at Norristown, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Shuttle-B0X Motions for Looms, which improvement is fully set forth in the following speciiication and accompanying drawings.

My invention relates to improvements in box-motions for looms; and it consists of a novel combination and arrangement of parts hereinafter set forth.

Figure l represents a partial side elevation and partial vertical section on line so m, Fig. 2, of a box-motion for looms embodying my invention. Fig. 2 represents a partial end view and partial section thereof on line of: oc, Fig. l. Fig. 3 represents a View of a detached portion.

Similar letters of reference indicate corresponding parts in the several gures.

Referring to the drawings,A designates pinions which are mounted on the frame A', the latter being connected with or forming part of the frame proper of the loom, and has mounted on its side the studs c, carrying the blocks B, which play in slots or recesses C of the arms D of the levers D', the latter being pivotally mounted onthe frame A' and having connected with them the depending links E, which are attached to the swinging levers F, from which depend chains G, which are connected with box-levers, it being noticed that the slots or recesses C of the arms D extend in horizontal or somewhat horizontal direction.

In the arms D, 'below the recesses C, are recesses H, which receive the axial pins J of the pinions A, said recesses H passing over said pin as the arms D oscillate, due to the action of the blocks B, which are carried to the right and left by the pinions A, it being seen that the latter receive reciprocating motions by the operation of the racks K and L, which mesh with said pinions and have connected with them, respectively, the bars M and N, the bar N being adapted to rise and fall without disengaging the racks from the pinions.

provided with a yoke V, which latter is engaged by a cam XV, which is mounted on a shaft X, to which motion is imparted by the gearing Y and shaft Z, the\arm U and shafts X Z being properly mounted on the frame A'.

On the upper side of the bar M is an inclined nger or lifter A2, which is adapted to engage with a roller or abutment B' on the frame A', and thus clear the recess in the bar YM from engagement with the lifter-bar R, so-

as to permit the return movement of the latter free from said bar. On the under side of the bar M is the inclined shoulder D2, which is adapted to be-engaged by the shoulder E', which rises from the end of the bar N and thereby separates said bars so as allow the free passage of the lifter between them for the purpose hereinafter explained.

F' designates a pattern-wheel which is adapted to actuate the bar N, whereby the latter will be raised and permitted to drop relatively to the design or pattern of goods to be woven.

The operation is as follows: When the riser on the pattern lifts the bar N, the recess Q then receives the lifter-bar Rand causes said bar N to be engaged by said lifter-bar. The latter now advances and carries with it the bar N, thus rotating the pinion A and thereby operating the lever D so as to raise the attached box-lever. The shoulder N on the Abar N clearing the pattern-wheel permits the said bar to drop to such extent that the recess Q leaves the lifter-bar. The shoulder D2 then engages the shoulder E', thus pre* venting the bar M from dropping to the same extent. Vhen the lifter-bar returns it is clear of the bar. of the bars N and M drop and the bar M has its recess P engaged with the lifter-bar, which latter advances and carries with it the bar M Vhen a sinker occurs, both IOO and causes the rotation of the pinion in reverse order, whereby the lever D is moved so as to lower the attached box-lever. The ingcr A2 now engages with the roller B and lifts the bar M clear of the lifter-bar, whereby when the latter returns it is free of the said bar M, and so the operations maybe repeated. Should, however, after a riser on the patternchain there be a second riser instead of a sinker, as has just been stated, then instead of both bars dropping they will be held up and the bar will remain free of both recesses Q and P, and work in the space between the bar without causing a shifting or rotation of the pinion, the box-lever thus remaining at rest or in the position it last occupied. Vhen the block: is raised by the pinion, it enters the recess and operates the lever D, so as to either raise or lower the attached box-lever, as the case may be, but when said lever has made its throw, as the pinion is locked by stopping of the racks, the said lever D is locked until the next movement of the pinion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`- In a box motion for a loom, a frame, pinions A mounted thereon, bars M and N with racks engaging said pinions, and having recesses in their lower and upper faces respectively, the reciprocating lifter bar R movable in a slot in said frame adapted to engage the recesses in the bars M and N, a pattern wheel adapted to raise and lower said bars M and N, the levers D' with arms D having the re eesses C and H therein, the blocks B carried on the sides of said pinions A, in said recesses C,

` the axial pin of said pinions A moving in said respectively, said parts being combined substantially as described.
